Abstract: A method is provided for controlling access by a series of users to a space and/or particular service. The method includes the following steps for each of the users: requesting access to the space and/or service by the user, issuing an access authorization or denial; opening of an access to the space or the service, if an access authorization was issued; estimating a waiting period prior to accessing the space and/or service when the opening is delayed; and issuing to the user at least one piece of information representative of the waiting period. The estimation step takes account of a number of users having already passed through the access and still waiting in the space and/or the service.

The method includes, for at least one of the transactions: emission, by the transaction device, of at least one first signal including a message relating to the transaction; receipt, by at least one mobile terminal, of the at least one first signal; transmission, by the mobile terminal, of a second signal including at least the message, to at least one banking organization; association, by a server of the banking organization in charge of the transaction, of the message with at least one datum relating to the transaction, and marking of the transaction as a pre-checked transaction.

Abstract: A computer implemented method includes collecting logged operations associated with a computation resource. Permitted operations for the computation resource are inferred based at least in part on the logged operations. A computation resource is augmented to block all operations that can be performed by the computation resource except the permitted operations.

Abstract: A device is provided for logging data in Braille. The device includes a touch-sensitive surface and is configured to detect a plurality of pressures on the touch-sensitive surface, wherein the plurality of pressures form a Braille character, construct an image formed from the points associated with the plurality of pressures; and recognize the Braille character based on an analysis of the image.

Abstract: A method for preventing secret code manipulation in a data processing device, such as a smart card, to which a presented code is applied. Prior to implementation of a code transforming function in the processing device, the secret code is transformed into a transformed secret code in the card. For each use of the card, the presented code is transformed into a transformed presented code in accordance with the implemented transformation function. A comparison of the transformed secret code with the transformed secret code in the card is then performed.

Abstract: A biometric authentication method if provided for an individual to be authenticated amongst a very large quantity of individuals with an authentication system storing a set of reference information each associated to one of the individuals. The reference information is distributed across a plurality of sub-databases. The method includes a phase of adding reference information representative of a new individual, including selecting the sub-database that is best adapted to store the reference information to be added.

Abstract: An electronic payment terminal and method are provided for printing tickets. The method includes: carrying out payment transactions with the terminal; after each transaction, simultaneously printing several tickets concerning the transaction made. Accordingly, when several transactions are carried out successively, the time required for printing the tickets is shortened since the tickets are printed at the same time.

Abstract: A method for controlling a pointer having a position determined by the position of at least one end of a member on a touch screen. An offset is inserted between the position of the pointer and that of the end of the member for driving movements of the pointer such that the end does not have to cover an object displayed on the screen in order to effectively select the object.

Abstract: A method is provided for displaying the properties of a source code element of a computer program being edited. The includes selecting, within the source code, the source code element; searching, within the source code, a set of related code elements of the selected source code element, the elements of the set comprising typified properties; creating a data structure comprising the properties of the code elements of the set of code elements; grouping, within the data structure, the properties in function of their types; displaying the properties grouped within a portion of a display displaying the source code.

Abstract: A portable device is provided, which includes a touch screen and at least one area bearing reference information, referred to as a reference area, which can be identified by detecting a variation in the surface state on the device.

Abstract: A method and apparatus are provided for validating a transaction on a transactional terminal, the transaction being associated with a user. The method includes a step of decoding a validation code preliminarily generated and displayed by the transactional terminal, entered by the user in a validation message, and transmitted by a mobile device of the user to an entity of a telecommunications network to which the mobile device and said transactional terminal are connected.

Abstract: A method and apparatus are provided for biometric authentication of a user to be authenticated, from among a plurality of users, with an authentication system storing a set of pieces of reference biometric data, each associated with one of the users. The method includes providing, by the user to be authenticated, a piece of biometric authentication data by a device for obtaining biometric data from a transactional terminal. A subset of the set of pieces of reference biometric data stored by the authentication system is searched for a piece of reference biometric data corresponding to the user to be authenticated as a function of the piece of biometric authentication data. The step of searching includes filtering the pieces of reference biometric data as a function of: a base station of a mobile communications network; and a set of mobile devices for which a connection indicator is activated for the base station. The transactional terminal is substantially near a zone of coverage of the base station.

Abstract: Patching a read-only memory, including a program executable by a processor is performed with a MRAM-based CAM device connected to the address bus and comparing in the background the addresses requested by the processor with the elements of a vector of addresses. The match-in-place operation is done in parallel on all the elements of the vector and typically is performed in less than a clock cycle. If a match is found, the CAM device outputs a diversion address that's used to retrieve a substitution machine code element from a flash memory that is presented to the processor in lieu of the one addressed in the ROM. This patching scheme is totally transparent, has little overhead, and extreme granularity.

Abstract: A method is provided for supplying data representative of transactions between a client and at least one merchant, via a banking institution.

The method includes a transaction phase, including: storing data representative of said transaction, in a statement server; acquiring and storing, in an illustrative data server, at least one information representative of a photograph and/or illustration representative of said merchant, called illustrative information. A supplying phase includes: creating the statement, associating to at least one of the statement lines the data representative of the transaction and at least some of the illustrative information, and/or at least one information pointing via one hyperlink to at least some of said illustrative information, called access information.
